Catullus 8

miser Catulle, desinas ineptire, et quod vides perisse perditum ducas.

Poor Catullus, stop being a fool and accept that what you see has finished and is over.

fulsere quondam candidi tibi soles, cum ventitabas quo puella ducebat amata nobis quantum amabitur nulla.

Once, suns shone brightly for you, when you always used to go where your girl led, loved by me more than any girl [ever] will be loved

ibi, illa multa cum iocosa fiebant, quae tu volebas nec puella nolebat, fulsere vere candidi tibi soles.

Then, when so many enjoyable things were happening, which you wanted and the girl didn’t refuse, truly the suns shone brightly for you.

nunc iam illa non vult: tu quoque impotens noli,

[But] now she doesn’t want that anymore: so you, since you can’t help it, must stop wanting it too.
